Can you claim that purity on your own?

Who may ascend the hill of the Lord? Who may stand in his holy place? He who has clean hands and a pure heart, who does not lift up his soul to an idol or swear by what is false.
(Psalms 24:3-4 (NIV))

A pure heart is all God really asks for. If your heart is pure, then all things that you are involved in will also be pure, for the heart leads us where it is focused. If your heart is focused on sin and perversion, then your life will be full of sin and perversion. If your heart is focused on God and His righteousness, then your life will be filled with those things.

It is said that you are what you eat. Perhaps that saying should be stated that you are what your heart desires. Jesus even stated that what goes into your body does not make you unclean.

Nothing outside a man can make him `unclean’ by going into him. Rather, it is what comes out of a man that makes him `unclean.’ ”
(Mark 7:15)

So then, it is possible for people to ascend the hill of the Lord!

This is an awesome thought, for all throughout the Old Testament, being in the presence of God meant certain death. This death was probably due to the fact that people are sinful and God cannot be around sin. We are still sinful, yet, we have a Savior who has paid the price for our sins. Jesus Christ died on the cross for all of us, and through His selfless act, we have the ability to be made white as snow in the sight of God.

A popular laundry detergent for baby clothes states that it is 99 and 99/100 percent pure. We have the ability, through Jesus Christ, to be 100 percent pure in the eyes of God.
